IMPROVEMENT IN CORN-PLANTERS.

To all whom, it may concern:

Be it known that 1', J. H. 130mm, of Elizal bcthtown, in the county ofHamilton and State I of Ohio,-have invented a new and useful ma chine,an Improvement in Corn-Planters; and I do hereby declare that thefollowing isafull, clear, and exact description of the construction andoperation of the same, referencebeinghad to the annexed drawings, makinga part of this specification, in which- Figure 1 is a perspective view.Fig. 2 is a vertical section. Figs. 3, 4, 5, 6, 7, S are sections ofparts.

In Figs. 1 and 2, BB is the plow-stock; G D, the plow; I-I,coveriiigilukes; G, conical reservoir; X, handle; I I I, tilting-pins;F, conducting-spout; E, block or bottom.

In Fig. 3, K K is the inner ring; a a, oblong holes; 1), slot.

In Fig. 5, L is the outer or thick ring, andK is the inner. c c areoblong holesin the outer ring, and a. a in the inner ring. Z) is itsslot and screw. I I are tilting-pins.

In Fig. 6, G is the conical reservoir, which is turned from right toleft by the handle X; L, outer ring; 0 e, cavities; a (1., holes tosupply c c with corn.

Fig. 4 is the cap to fit on the conical reservoir.

A is a disk, having a flange, M M, upon its periphery. axis a segmentalflange placed from O upward a sut'flcient distance from M M to receiveFig. 6.

q is an opening in II M for the exit of the corn.

t is a slot in the segmental flange.

O 0 is a wire spring, playing in the slot to force the corn out of theholes into the spout; S S, height of corn in the reservoir; 1:,segmental space.

\Vhen Fig. 6 is inserted into Fig. 4: and turned from right to left, thecorn falls through the holes a a, Fig. 6, and draws back into thecavities c 0, while passing from O to S, M M, Fig. 4, forming theoutside wall, and K K, Figs. 3 and 5, the inside, and is carried up tos. From 8 to v. The surplus or loose corn is shaken off and falls backinto the reservoir. Thus struck measure is carried up to '0. From o toqit goes downward and the corn falls toward a a, Fig. 6, and would fallback into the reservoir but for the segmental flange over which therings pass. The exact measure is thus retained until opposite 9, when itis forced out by the spring 0 0 into the conductingspout F, Figs. 7 and2.

In drilling, the operation is better performed by using a hopper, n,Fig. 8, in the place of the segmental flange. n, Fig. 8, is set to thedisk A, so as to convey the corn through an orifice in A at the point ofthehoppern, while the flange M is made without the opening (1, Fig. 4.

Fig. 7 shows the conducting-spout. 11 is the bevel on which the pins II,Fi 6, strike. at is one of the ears 011 which thespout is hinged. E isthe block or bottom, which is fast to the stem, Fig. 2. The pins I I areset ahead of the cavities, so as-to act on the spout and deliver thecorn in. the bottom resting on the block E and replace itself before thecorn is delivered for the next hill in dropping checkrows.

To enable others to make and use my improvement, I will describe itsconstruction.

I first construct a conical reservoir six or more inches in diameter atits base, of sheetiron. I then secure to it a thick cast ring about aninch wide, with oblong holes in it for seed-cavities, and between theseI insert holes forthe tilting-pins. I then make another ring of the samewidth, of tin, with oblong holes to match the thick ring 011 the insideand make it fit tightly. I then solder to it a small tap for a screw,which works in a slot in the outer ring, by which it may be moved forthe purpose of making the cavities larger or smaller and securing itfast. I then make a disk of sheet-iron the diameter of the thick ring. Ithen attach a flange three-iburths of an inch in width, of the samematerial, and one inch less in length than the circumference of thedisk, for the purpose of leaving aplace of exit for the corn to thedisk. I then make a segmental flange the same width and one-quarter ofthe circle in length. In this I cut a slot one and one-half inch inlength. I then secure it to the disk from r to 0, Fig. 4:, so as toleave space enough for the rings, as shown in Fig. 5, to pass between. Ithen set the wire spring 0 0 so as to play in the slot, Fig. 4. \Vhen itis made for drilling, I substitute a hopper in the place of thesegmental flange, which I make three-quarters of aninch wide at the top,and circular, so as to fit the ring. I then fasten it to the disk at thelower point of the hopper, and make a hole through the disk for the exitof the corn. In this case I make no such openingin the outside flange.In the center of the disk I make a hole to secure the revolving handle.I then insert the handle 0c, and then attach the whole to the stationaryplowhandle. The operator then grasps the handle and by a simple turn ofthe wrist revolves the droppingrings one space at a time. I thenconstruct a spout and pivot it to the stem of the plow, so that theweight of the upper end will hold the nozzle over the block or bottom Efor retaining the corn. At
